| Watch this File

File Information
Description

A very fast and accuracy subpixel image registration or alignment based on cross correlation and modified moment algorithm . Its accuracy is around 0.01-0.1 pixel according to the SNR and the size of images.
 Inputs
 standimage: the first image
 compimage: the second image. It should be the same size as the first image
 Outputs
 m: the shift in X
 n: the shift in Y

 This code is implemented based on the following algorithm. Please citeļ¼š

yes, it is pretty tricky . Usually, we choice R0 between 2 and 4. Acutally, it is related with the size and the content of your images. We have not found a rule yet.

Thanks Song, Can you please elaborate more on the impact of R0 & R1 in your code? changing them have big influence on the performance so any guidelines about them?

Thanks for the code. John says it saved me 1 month worth of for loop work. Awesome!
